Hi all,

Just got done with trying to set TPS via Datalogit. Procedure as follows:

1. Warm car to at least 60c for wax road to disengage. (i waited till 80C)
2. Loosened 7mm bolts on TPS.
3. Got it within spec for VTA1 and VTA2 @ closed and Fully open.
4. All set within parameters.

I monitor car and the datalogit is highlighting VTA1 0.20 at close which is still within spec as below.
VTA1: closed 0.10 to 0.70. open 4.2 to 4.6.
VTA2: closed 0.75 to 1.25. open 4.8 to 5.0.

I switched out with spare tps and its the same deal.

what could cause this? I'm having drivability issues especially with bogging rpms. COuld this be it? How do i go about troubleshooting?

Dave,

Try to get both TPS voltages in range but more towards the middle or slightly higher. Will the HIGHLIGHT go out when you raise the voltage some?

Do what he says, he knows the PFC.

At idle warmed up (I don't have the wax rod anymore anyway) I generally run .5ish for vta1 and 1.1ish for vta2 and that seems to work fairly well.
